I TER HEATER AND rumrrna.

Application filed April 30, 1917.

To all whom it may concern:

Be it known that I, VILLIAM H. MORGAN, a citizen of the United States,residing at Marseilles, in the county of La Salle and State of Illinois,have invented a new and useful Tater Heater and Purifier, of which thefollowing is a specification.

It is one object of the invention to pro vide a novel means whereby feedwater may be heated before it is delivered to a boiler, the constructionbeing such that it will be impossible to feed the water to the boilerbefore the temperature of the water is raised.

Another object of the invention is to provide novel means whereby thewater may be filtered before it is delivered to the boiler, after havingbeen heated.

A further object of the invention is to provide, in combination withmeans for heating and purifying the feed water, novel means whereby theflow of the water may be controlled, and whereby the necessary blow-ofi'may be supplied.

It is within the province of the disclosure to improve generally and toenhance the utility of' devices of thattype to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, withoutdeparting from the spirit of theinvention.

eluding a shell 9, a rear flue sheet 10 and a forward flue sheet 11, theflue sheets 10 and 11 carrying flues 12. The numeral 1% denotes the headof the boiler, the head 14 cooperating with the forward flue sheet 11 todefine a smoke box 15 communicating with a stack 16. The water space ofthe boiler is shown at 17. The construction above described embodies anordinary boiler structure, and no novelty is claimed therefor, saving inso far as it may cooperate with elements hereinafter described. Thedevice forming the subject matter of this application is adapted to beconnected with boilers of diflei-ent kinds, but the foregoingdescription will enable those skilled in the art to understand how thepresent invention is used.

A water heating conduit passes upwardly into the smoke box 15,longitudinally of the water space 17, and upwardly through the topportion of the shell 9 of the boiler. This conduit includes a pluralityof connected lengths of pipe, shown at 18, and located in the waterspace 17 above the fines 12. By

means of a coupling 19, one of the lengths 18 of pipe is united with ahorizontal pipe 20, passing through the forward flue sheet 11. The pipe20 embodies a vertical extension 21 passing downwardly into the smokebox 15 and outwardly through the bottom of the smoke box. The extension21 includes a blow-ofi' nozzle 22 located below the smoke box 15 andprovided with a hand valve 23. The numeral 24 indicates a source ofwater supply which communicates with the pipe or extension 21. By meansof a coupling 25, another of the lengths 18 of the pipe is united withthe vertical pipe 26 passing upwardly through the top of the boilershell 9. The pipe 26 has a horizontal extension 27 in which is located asafety valve 28.

Mounted on the rear wall 2 is a base plate 29, to which is connected thelower end of a tubular casing 30 surmounted by a removable lid 31. Thebase plate 29 has a socket 32 into which is threaded a stub pipe 33supporting a T-coupling 34 with which is connected a blow-oft pipe 35,passing horizontally through the casing 30, and supplied, exteriorly ofthe casing, with a hand valve 36. The numeral 37 denotes the reducedstem of a settling tank 38 which, roughly speaking, is of funnel shape.The stem 37 preferably is threaded into the upper end of the coupling34." The stem 37 has anabutment 39 engaged by a plate 10 havingperforations 41. Disposed below the plate40 is a filter 42 which may bevariously constructed. The

filter 42 in place and for supporting the settling tank 38 may bealtered, within the scope of the invention. The plates 40 and 43 fillthe casing 30 transversely. V

The horizontal. extension 27 of the pipe 26 has a depending end 46passing through the lid 31 of the casing 30 and extended downwardly intothe open top of the funnel-shaped settling tank 38, so as to dischargethereinto. A horizontal pipe 47 opens into the casing 30 below thefilter plate 4-3 andis provided with a hand. valve 48. The pipe 47communicates with a ver tical pipe 49 carrying a valve under the controlof an operator, the upper end of the pipe 49 being connected to the pipe27. Interposed in the pipe 27 between the pipe 49 and the depending end46 of the pipe 27 is a hand valve 51. The numeral 52 denotes ahorizontal pipe with which the vertical pipe 49 communicates. One end ofthe horizontal pipe 52 passes rearwardly through the wall 2 and isprovided, exteriorly of the wall 2, with 'a hand valve 54. The other endof the pipe 52 passes through the rear fiueshect 10 and terminatesin adischarge head 53 located in the water space 17 of the boiler. The pipe47, the lower end of the pipe 49 andthe left hand end (Fig. 1) of thepipe 52 form a discharge conduit lead-' ing from thecasing 30 to thewater space 17 of the boiler. A blow-elf pipe leads from the boilershell 9 and passes rearwardly through the wall 2, the pipe 55 beingsupplied with a hand valve 56.

Let it be supposed that the valves 56, 54, 36, 50 and 23 are closed, andthat the valves 51 and 48 are open. Then water enters the pipe 21 by wayof the water supply 24 and traverses the pipes 20, 18, 26, 27 and 46.The water, as it moves forwardly and rearwardly through the pipes 18 isheated and is delivered in a heated condition through the pipe 46 intothe settling tank 38. The heavier portions of the impurities of thewater move to the bottom of the settling tank 38, and the water flowsover the upper edge of the settling tank 38 and passes downwardlywithinthe casing 30, the water passing through the perforations 41 ofthe plate 40, through the filter 42, through the perfo rations 44 of theplate 43 and then into the bottom of the casing 80. The water then 7 vflows through the pipe 47 through the lower end of the pipe 49, throughthe left hand end (Fig. 1) of the pip charged through the head 53, intothe water e 52, and is dis-- space 17 of the boiler,- in a heated andtheroughly purified condition, the function of the filter 42 being" toremove the lighter impurities, which. have not gravitated to the" bottomof the settling tank 38.

Should the water be superheated in the pipes 18, or should unduepressure be:- created from any other cause in the water supply conduit,this pressure will be relieved by the safety valve 28. The boiler may beblown off in the usual way through the pipe 55 when the valve 56 isopened. The fiow of water to the settling tank 38 may be controlled bymanipulating the valve 51. If the valves 54, 48 and 51 are closed, thevalves 50 and 23 being open,then

steam will traverse the pipe 52, the pipe 49, I the left hand end of thepipe 27 (Fig. 1)

the pipe 26, the pipes 18, the pipe 19, the pipe 21, and the nozzle 22,to blow out the water supply conduit, from the front of the boiler. Ifit is desired to clean or repair the casing 30 and filter parts carriedthereby, then the valves 51 and 48 may be closed, cutting out the filtermechanism,the valve 50 being open. Under such conditions, the watermoving upwardly through the pipes 26 and 27, having been heated, willpass downwardly through the lower end of the pipe 49 and through theleft hand end of the pipe 52, the water thus entering the boiler withouthaving been filtered. If the valve 48 is closed, the valves 29, 50and 51being open, then the filtering mechanism can be blown oil? through thepipe 35. .By opening the valve 54, the pipe 52 can be blown offthroughout its length.

After the feed water has been heated, the scale-forming material iscaught for the most part in the settling tank 88, and if any of thescale-forming material is not retained in the tank 38, such material isextracted when the water passes through the filter 42. As a consequence,the water enters the boiler free from scale-forming material, mud andthe like, thereby avoiding foaming, bagging of the sheets, leaky tubesand the like.

Having thus described the invention, what is claimed is 1. In a deviceof the class described, a-

boiler; a casing; a settling tank in the easing and having an outlet; avalve controlling the outlet; a filter "inthe casing, the settling tankoverflowing onto the filter; a discharge conduit leading from the casingbelow the filter, to the boiler; and a water heating conduitpassing'through the boiler, one end of the water heating conduitentering the casing and discharging intothe settling tank.
